ADB and permissions

[Guest elkay62]

Hi folks,

I'm trying to copy in a new gps.conf to /system/etc

I'm on 1.6, and have rooted using UA, which appears to have worked successfully.

My current "mounts" are:

# mount

mount

rootfs / rootfs ro 0 0

tmpfs /dev tmpfs rw,mode=755 0 0

devpts /dev/pts devpts rw,mode=600 0 0

proc /proc proc rw 0 0

sysfs /sys sysfs rw 0 0

/dev/block/mtdblock8 /data yaffs2 rw,nosuid,nodev 0 0

/dev/block/mtdblock3 /cache yaffs2 rw,nosuid,nodev 0 0

tmpfs /sqlite_stmt_journals tmpfs rw,size=4096k 0 0

/dev/block/mtdblock6 /system yaffs2 rw 0 0

/dev/block/mtdblock7 /lgdrm yaffs2 rw,nosuid,nodev 0 0

/dev/block//vold/179:1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=

1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,s

hortname=mixed,utf8 0 0

#

I have tried the following commands, before "pushing" the file:

# mount -o remount,rw /dev/block/mtdblock6 /system

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system

This is what I get when I try to copy the file:

C:\Users\elkay>adb push gps.conf /system/etc

failed to copy 'gps.conf' to '/system/etc/gps.conf': Permission denied

I have managed to remove the original using rm, but still get the same error message.

Any ideas?

Any dummies guide to adb would also be appreciated :-)

regards

elkay

PS: also tried this:

C:\Users\Leslie>adb remount

remount failed: Operation not permitted

Copy it into the directory you want using Root Explorer.

Copy it into the directory you want using Root Explorer.

Are there any free alternatives to Root Explorer on Market?

Not that I am aware of.

adb shell

$ su

# mkdir /data/yourname

# chmod 777 /data/yourname

# exit

$ exit

adb push gps.conf /data/yourname

adb shell

$ su

# mount -o remount,rw /dev/block/mtdblock6 /system (copy :P)

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system (copy :D)

# mv /data/yourname/gps.conf /system/etc

try droid explorer

[Guest elkay62]

First

I managed to copy my file in after doing a chmod on /system/etc

However, for the sake of learning...

Second

@merrymenvn

I understand the approach here, looks good.....except, can you explain what these do?

# mount -o remount,rw /dev/block/mtdblock6 /system

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system

Also, when I got to

mv /data/pics/gps.conf /system/etc

I got

failed on '/data/pics/gps.conf' - Cross-device link

Any ideas?

Third

@flyboyovyick

Droid Explorer looks very interesting. It may get the honour of being my first paid-for app (62p!)

Fourth

Back to First - I can't remember what chmod instruction I used, but I know I should put it back the way it was - what chmod is required to do this?

Thanks for all the help folks!

I'm sorry, I havent tested.

You can't execute adb push gps.conf /system/etc because only root have permission to write in /system/etc, but you are not root, you are shell user.

# mkdir /data/yourname

# chmod 777 /data/yourname // make a folder and enable write permission for anyone.

# exit

$ exit

adb push gps.conf /data/yourname // copy gps.conf to writable folder on your phone

adb shell

$ su

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system (copy ) // remount to write to /system because default is read only (ro)

# mv /data/yourname/gps.conf /system/etc // error here

Change mv command to:

# rm /system/etc/gps.conf //delete old file

# cat /data/yourname/gps.conf > /system/etc/gps.conf //copy new file to /system/etc

check content of new file:

# cat /system/etc/gps.conf

All commands:

adb shell

$ su

# mkdir /data/yourname

# chmod 777 /data/yourname

# exit

$ exit

adb push gps.conf /data/yourname

adb shell

$ su

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system

# rm /system/etc/gps.conf //delete old file

# cat /data/yourname/gps.conf > /system/etc/gps.conf  //copy new file to /system/etc
